Be it known theta SHeBL-ss Mo'iiz, a resident tofnshigpy iii, .the county of Eem-ef and State of llennsyivenie, have inventefl e new mid useful mp'ovement 'in Send-Biest Machines; and de hereby @e-l ciere the eiiowinc te'be a fedi) dem", and exact description thereof.

My invention reistes to -send-biest machines.

he Object of my invention is to in ipz'ove machines of this character in such a. Way es te grovii'ie foi' wide. varietion in 'the edjusment so" as to adapt the machine for the smid-blasting of were of different shapes and sizes, so that ail the parts to be fosted Wiii be -reached by the sand-blast, and e uniform firestiiigo the waive obtene.

To these etuis my invention comprises, geueaiiy stated, :i suitable ieeeptacle containing salici, s rotery eiihplpcmeais lol reversing the direction et otetion et said air-@ e, send-pipe connecte to said mi'- pipe, and e rotary support for the art-ide to be opeeted on in position to be acted on by sand-Mesi.' in `the dym'iigs.; igure l is s 'sectional 'ation o; improved machine; Fin'. 2 -s section on the line (2-2) Fig.- l;
